It seemed unclear that the patch addressed all the issues raised in the ticket, and looking at random patches still requires dev time. It is a different story when someone else actively works on getting it upstreamed and working on resolving any issues. It's about who volunteers to do the hard work.
Given that no one stepped up to do it yet and random users chimed in with aggressive and/or unhelpful noise, locking the issue was adequate.
I find it concerning how much abuse GNOME devs get, and I can completely understand that they respond like this.
